Intel’s Core i7-8700K has been overclocked by German overclocker Dancop on the ASUS ROG Maximus IX Apex (Z270) motherboard. Remember, the i7-8700K is not supposed to work on the Z270 chipset, although CPU-Z screenshots do confirm he was able to get the chip to work on the chipset. He is using a custom “0084” BIOS dated 11th June, 2018. With the chip running on the board he then overclocked it to 7344 MHz! With that he was able to break and capture the Super Pi – 32M world record!
Now there was one catch with this though, he disabled 3 of the 6 cores on the Core i7-8700K as well as HyperThreading. So technically we have a 3-core, 3-thread chip running at a blistering 7344 MHz, which was able to crunch through Super Pi 32M in 4 minutes and 7.609 seconds. He was able to achieve the clock speed of 7344 MHz by dialing the multiplier up to 73x and the Vcore voltage up to 1.984 V. He used a liquid-nitrogen evaporator to keep both the CPU and VRM cool during his overclocking session.
